Gcc 将静态库文件添加到makefile

我有以下由python脚本执行的makefile：

这将解决问题。我的lib是libmylib.a文件。然而，控制台仍然输出带有未定义的函数引用的错误。我应该换什么？ python脚本将源、对象、标题和标志作为参数动态传递到目录的路径。

它应该是：

LIBS=-lmylib

编译器将在指定的库中预先添加

lib

并附加

.a

，使其查找名为

libmylib.a

的库文件，这正是您想要的。

谢谢您的回答。还是不行，但我相信你是对的。不知道我做错了什么…是否可以打印提供给makefile的一些参数，以便我能够检查路径等？传递

-v

将导致它打印其他信息，包括库搜索路径。将其添加到

LD_标志中
